One has slayed millions with a killer voice that led one of the biggest and baddest rock 'n' roll bands of all time. The other led armies of thousands into battle in 'The Two Towers,' the second flick in the big-screen adaptation trilogy of J.R.R. Tolkien's epic fantasy book series 'The Lord of the Rings.'

At age 63, Led Zeppelin singer Robert Plant's famously curly mane has been tamed somewhat, but he still proudly wears it long and flowing freely, much like that of King Theodon (played by British actor Bernard Hill). Both also have very similar goatees, that off-in-the-distance gaze and even -- most amazingly -- matching patterns in their facial creases.

We're betting that King Theoden could take the stage in Plant's newest musical endeavor, Band of Joy, and people would be fooled into thinking he was Plant -- at least until it was time to open his mouth and sing.
